A team of scientists has developed contact lenses that enable users to perceive infrared light, which is typically invisible to the human eye. Unlike traditional night vision goggles, these contact lenses are designed for direct application to the eye, potentially offering a more convenient and discreet way to extend visual capabilities. The technology is currently in the experimental phase and is not yet available for commercial use. According to the research team, the lenses could have significant applications in various fields, including security—where detecting heat signatures or hidden objects could be beneficial—medicine, by assisting in diagnostics or surgical procedures, and industry, for tasks such as equipment monitoring or quality control. The researchers emphasize that further testing and development are necessary to ensure the safety and effectiveness of the lenses before they can be made widely available to the public. This breakthrough could also pave the way for other wearable devices that enhance or alter human vision, including potential benefits for individuals with color blindness.
